Diagnostic Indicators
Health indicators are located on the front panel of the adapter module,
See Figure 1.1. They show both normal operation and error conditions in your
remote I/O system.
In addition, an alphanumeric display (net address/status) provides status code
indications when an error occurs during initialization or operation.
A complete description of the diagnostic indicators and status display and how
to use them for troubleshooting is explained in Chapter 5.
Network Access Port (NAP)
The network access port provides a bidirectional electrical interface for
programming, maintenance, and I/O monitoring devices in both redundant
and non-redundant connections. See Figure 1.1 connecting programming
terminals to the network using the NAP above.
